Patented Dec. 19, 1944 2,365,661 METHOD or 'rwls'rlNG wma Albert E. Winslow, Mystic, Conn.. assigner to Atwood Machine Company, a corporation of Connecticut Application August 21, 1943, Serial No. 499,576

` s claims. (orsi-16o) This application relates to the laying of wire in which one strand is helically wound about another or a. plurality of strands are helically wound about a core.

In wire twisting it is usual `to take from several packages the several strands which are to be used Where it is desired that these strands be laid without torsional twist the supply packages are turned in an amount to lay the wire without such torsional twist.

Oney of the objects of this invention is to provide a method for making wire cable in which the strands may be laid without torsional twist and by simple machinery. a

Another object of this invention is to accomplish this simplified result by'v utilizing two 'simple steps of the handling of the wire and with the packaging after each step whereby more simplified machinery and much faster operation may be had.

Another object of the inventionis to provide a cable in which the helically laid strands will be more evenly laid than heretofore.

Another object of the invention is to provide a cable the strandsof which are free from torsional twist in themselves.

With these and other objects. in view, the invention consists of certain novel features ofconstruction, as willbemore fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 diagrammatically illustrates the drawing pf wire from three diil'erent spools to parallelly package the strands on a single spool;

Fig. 2 illustrates the parallel wires as being drawn from the spool of Fig., l upon which it is packaged and then being twisted or laid;

` Fig. 3 is a top plan view of the ilyer and package as illustrated in Fig. 2; y

Fig. 4 is a view similar to Fig. 2` illustrating a modied form in that a core strandis passed up through the package about which the several strands are laid.

In proceeding with this invention I take from a plurality of packages IIJ, II, and I2, each having a single strand material thereon, the strand Il, I5, and IB, guiding them in parallel relation by the fingers II and traverse bar I9 onto a package I9 comprising a suitable barrel 20 and ends 2|. This package I9 is driven to package the strands in parallel relation, all as described and shown in more detail in 'my co-pending application Serial No. 508,818. a l

The drawing of the wire from thefseveral single strand packages may be accomplished at a relatively high rate of speed and the packaging on the package I9 thus accomplished quickly.

The package I9 presents the strands in a. form' in which they may be laid in helical fashion by a subsequent operation and in Fig. 2 I have illustrated` this package Adesignated generally I9 as mounted upon a vertical 1spindle 24 upon which there is also mounted a cap 25 over which the several strands I4, I5 and I6 are drawn upwardly by the feed rolls 25. As the strands I4, I5, and I6 are drawn upwardly they are equally' separated. and guided in equally angular relation by arms 26, 21, and 28 of a nyer designated generally 29 (see Fig. 3) which is mounted upon the spindle and cap and controlled by spring 30 so as to permit relative rotation of the flyer with respect to the cap and package, all as illustrated and described in more detail 'in my co-pending application Serial No. 499,575.

The package I9 is driven so that helical laying 'of the wires I4, I5, and IB occur. The number of helical turns will depend uponthe differential of movement between the driven package I9 and the flyer 29. The flyer 29 will turn suilcient to unlay the parallel wrapping or winding of the three parallel wires on the spool while any added revolution given to the package will result in the helical disposition of the wires one about the other adjacent to the feed rolls 25 which draw the wire upwardly. The wires as they leave the cap 25 travel in substantially a, conical path and extend substantially up tothe nip and feed rolls` 25. By reason of the arms 28 of the flyer being equally disposed the strands are all equally disposed and an even helical laying of the cable results. Also, by reason of these equally arranged arms each of the strands I4, I5, and I8 are drawn tangentially from the body of the package I9 as will be seen in Fig. 3 which is of advantage.

In some cases it is desirable to provide a core strand 30 as shown in Fig. 4 and in this case the spindle 9| will be provided with a hollow bore 32 and this core strand 30 will be guided over aprises packaging in parallel relation on a single package a plurality of strands, rotating said package and drawing from said package the plurality of strands thereon from equally spaced points in the surface of the package and helically posi tioning said strands one about the other in a cable formation. e

The method of laying wire cable whichcomprises packaging in parallel relation on a single package a plurality of strands, rotating said package and drawing from said package the plurality of strands thereon from equally spaced points in the surface of the package and helically positioning said strands about a core strand passed through the center of said package.

3. 'I'he method `of laying wire cable which comprises packagingin parallel relation on a single package a plurality of strands, rotating said package and drawing from said package the plurality of strands thereon from equally spaced points in the surface of the package and helically positioning said strands about a core strand passed into the center of said strands through the center of said package to provide a cable formation.
